Python 3.8.0b4 is now available for testing

This
release is the last of four planned beta release previews. Beta
release previews are intended to give the wider community the
opportunity to test new features and bug fixes and to prepare their
projects to support the new feature release. The next pre-release of
Python 3.8 will be 3.8.0c1, the first release candidate, currently scheduled for 2019-09-30.

Call to action

Westrongly encouragemaintainers of third-party Python projects totest with 3.8during the beta phase and report issues found tothe Python bug trackeras
soon as possible. Please note this is the last beta release, there is not much time left to identify and fix issues before the release of 3.8.0. If you were hesitating trying it out before, now is the time.While the release is planned to be feature complete
entering the beta phase, it is possible that features may be modified
or, in rare cases, deleted up until the start of the release candidate
phase (2019-09-30). Our goal is have no ABI changes after beta 3 and no
code changes after 3.8.0c1, the release candidate. To achieve that, it
will be extremely important to get as much exposure for 3.8 as possible
during the beta phase.

Please keep in mind that this is a preview release and its use isnotrecommended for production environments.
